Training? Who Taught You to Modify the Machine Like This?

[Mechanic Girl Modification] + [Racing Competition] + [Novel Theme] + [Old Taste] + [Sweet Cultivation~] This book is also known as "Who Says Top Modifiers Can't Be Top Drivers?" My name is Su Chen, the chief racing car modifier in China. I encountered a semi-trailer with all risks on the road, but I couldn't defeat it with all my strength, so I got the time travel package. This is a world where racing is supreme. There is a kind of girl called mechanized girl who can transform into a racing car and race on the track. I thought that I could make a living in this world and achieve the freedom of picking up girls by opening a modification shop with the modification skills of my previous life. As a result, because I didn't have a modification certificate, the modification shop was on the verge of bankruptcy. In order to overcome the difficulties and activate the system. I made a decision that went against my ancestors - giving it away for free. ——————————————— My name is Xingmeng. I am a mechanized girl who is disliked by female drivers because of poor performance. In order to help the driver pass the graduation assessment, I had to seek modification and upgrades everywhere. But because I didn't have much money, I was rejected by all modification shops. Until I saw the sign of this modification shop - free modification. It's just that this boss is a bit strange. The modification room he took me to didn't seem to be a proper modification room. If I was not mistaken, it seemed to be... a training room?
